Metallics NA1414V Anchors 1/4 x 1-1/4" Mtl Hm Dr Nail-In (Box 500)

The NA1414V is a 1/4 x 1-1/4 inch nail-in anchor. The 1/4 inch figure is the anchor diameter, so you drill a 1/4 inch hole, and the 1-1/4 inch length sets how deep the anchor body sits once the fixture thickness is accounted for.

That is the normal use for the NA1414V. With a 1-1/4 inch overall length, a thin item like a one-hole strap or a device box flange leaves roughly an inch of anchor in the base material, which is the usual working embedment for light electrical mounting. For thicker fixtures or standoffs, step up to a longer anchor so you keep the same embedment.

500 pieces per box. It ships as a box pack, so this is a bulk quantity meant for repetitive work such as running conduit strap, box, or channel fastening across a building rather than a one-off fix.

A nail-in anchor like the NA1414V is a one-shot fastener: drill the hole, push the anchor through the fixture into the hole, and drive the pin home with a hammer, which expands the body against the masonry. It is faster than a screw-type anchor for high-volume work but is not intended to be backed out and reused, so where you expect to remove the fixture later, a screw anchor is the better choice.
